## What is Killer Sudoku?

Killer Sudoku combines classic Sudoku logic with arithmetic. Every cage has a target sum, and digits inside a cage cannot repeat.

THREE DIFFICULTY LEVELS
Choose Easy, Medium or Hard, whether you are learning cage logic or looking for a tougher daily challenge.

TOOLS THAT HELP YOU THINK
Use pencil notes, unlimited undo and two free hints per puzzle. If you need another hint, you can choose to watch a short rewarded ad.

DESIGNED FOR FOCUS
A clear board, pauseable timer, saved games and best-time records keep the puzzle in the spotlight. There is no account and no timer pressure.

PLAY OFFLINE
Generated puzzles and all core gameplay work without an internet connection.

AVAILABLE IN 16 LANGUAGES
English, Vietnamese, Spanish, Portuguese, French, German, Italian, Indonesian, Hindi, Japanese, Korean, Chinese, Russian, Turkish, Thai and Polish.

Train your logic and mental math with a fresh Killer Sudoku puzzle whenever you want.
